【Hi-do】Flat Pure Copper Ring 3.0mm Width【Premium Coated Edition】

## Product Description Traditional Craft × Modern Culture Savoring the deep coloration of traditional Japanese beauty, "Hi-do," in its cleanest, most uncompromised form. This piece features a "flat band" finish, celebrated for its sharp edges and beautifully sleek, planar surface. The minimalist, linear silhouette strips away all excess, allowing the ring to exude a quiet yet powerful presence on your hand. Experience the distinct identity of Half Down, where the solid, metallic strength of pure copper coexists seamlessly with the inherent warmth of the Hi-do expression. ❖ 【New Feature: Premium Coating (Tarnish Prevention)】 To ensure you can enjoy the exquisite crimson born from the artisan's fire for a long time to come, this ring comes standard with our highest-grade protective coating (glass coat). Without compromising the natural luster or texture of the Hi-do copper, this piece has evolved into a premium specification that protects against tarnish caused by sweat or oxidation, allowing you to wear it daily with peace of mind. ※ Please note that this coating does not permanently guarantee resistance to heavy impact or severe abrasion. Bumping or rubbing the ring against hard surfaces may scratch the metal or cause the coloration to peel. We appreciate your gentle care. ❖ 【Traditional Technique: The Crimson of Hi-do】 Hi-do is an ancient Japanese metal art achieved by heating pure copper to high temperatures and controlling the oxide film with a special solution to bring forth a mysterious coloration—deep reds, oranges, and occasional purples—that seems to rise from within. Used since antiquity for traditional Japanese sword fittings, it is a profound metal expression unique to Japan that can never be replicated by artificial colorants. ❖ 【Artisan Craftsmanship and Dedication】 Altering its expression with the slightest variation in heat, Hi-do copper is an exceptionally delicate medium. To bring out the absolute unique crimson inherent to each ring, the artisan carefully judges the exact timing of the fire-firing for every single piece. Meticulous attention is paid during the hand-polishing process to ensure the flat surface showcases the beautiful coloration flawlessly without any distortion, while the edges are finished to sit comfortably and smoothly against your finger. ## Product Details Material: Pure Copper (Hi-do crimson finish with a tarnish-resistant premium coating) Design: Flat Band / Flat-surface Finish Band Width: Approx. 3.0mm Size: JPN Size 1 to 30 (An additional custom crafting fee applies for sizes 20 and above due to material costs and extended production steps.
